So what makes this stuff work via buildout is all version-pinning  
now?  Assuming you agree that packages released to the cheeseshop  
should be installable via easy_install, if distribution dependencies  
are version-pinned in a distribution's buildout.cfg, the same pin  
should be done in the setup.py install_requires= for that  
distribution. Otherwise running easy_install will never have the same  
result as running buildout when it comes to fetching dependencies for  
a particular distribution.  In general, buildout.cfg and setup.py  
should share all dependency information, or the version-pin in  
buildout.cfg should disappear.
